1/2 − (−3/4)
A 1/3
B 1/4
C 3/2
D 5/4
E 7/4
To evaluate the expression 1/2 - (-3/4), we need to rewrite the expression to have a common denominator:
1/2 - (-3/4) = 2/4 - (-3/4)
Next, we can simplify the expression:
2/4 - (-3/4) = 2/4 + 3/4
Now, we can combine the numerators:
2/4 + 3/4 = (2+3)/4 = 5/4
Therefore, the correct answer is D) 5/4.
1/2 - (-3/4) = 2/4 - (-3/4)
Next, we can simplify the expression:
2/4 - (-3/4) = 2/4 + 3/4
Now, we can combine the numerators:
2/4 + 3/4 = (2+3)/4 = 5/4
Therefore, the correct answer is D) 5/4.

32 + (-72.1) = -40.1
Therefore, the correct answer is B) -40.1.
The temperature in Antarctica at noon is 14°F. By 9:00PM, the temperature had dropped by 16.2 degrees. What was the temperature at 9:00PM?
A –2.2°F
B 2.2°F
C –30.2°F
D 30.2°F
A –2.2°F
B 2.2°F
C –30.2°F
D 30.2°F
To find the temperature at 9:00 PM, we need to subtract 16.2 degrees from the initial temperature of 14°F:
14°F - 16.2°F = -2.2°F
Therefore, the temperature at 9:00 PM was -2.2°F.
So, the answer is A) -2.2°F.
14°F - 16.2°F = -2.2°F
Therefore, the temperature at 9:00 PM was -2.2°F.
So, the answer is A) -2.2°F.

incorrect you just guessed lord..
Apologies for the confusion. Let's go through the simplification again:
To simplify 723 + (-514), we add the numbers. The negative sign before 514 means that we are subtracting 514 from 723.
723 + (-514) = 723 - 514 = 209
Therefore, the correct answer is 209.
